Hair highlighting applicator comb

ABSTRACT

A hair highlighting applicator comb is taught which has a hollow body with comb teeth, housing a dual cartridge containing a separate viscous bleach dye compound and a formulated viscous accelerator compound with a dual plunger rod having rack teeth aligned with the dual cartridge. A lever handle is pivoted onto the comb body and includes a ratchet arm pivotally engaging the lever handle and meshing with the plunger rod rack teeth. When the handle is manually pivoted the plunger rod slides linearly forward, and compresses the cartridge forcing the separate compounds to flow between selected comb teeth. A mixer, in fluid communication between the cartridge and the teeth, forces the separate compounds to blend together highlighting a person&#39;s hair in a spaced relationship when the comb is drawn through ones hair and the lever is manually compressed simultaneously.

p BRIEF SUMMARY OF THE INVENTION

Currently a person's hair is lightened by a beautician mixing twoingredients by hand into the form of a loose batter creamy mix. Theingredients consist of a bleach dye and an accelerator of peroxide inpaste form. The beautician in conventional salons normally use the foiltechnique which is comprised of separating strands of hair about oneinch wide and laying a strip of aluminum foil underneath then brushingthe hair with the mix and folding the foil around the hair.Traditionally a one inch space is allowed between the foil applicationsand the process is repeated.

The primary object of the invention is to permit a person to accomplishhair highlighting by self administration or with the help of anuntrained aide using only a self contained applicator comb. The combcontains all of the necessary ingredients and apparatus to evenlydispense a mixed dye composite. The applicator comb has teeth spacedapart the proper distance and a viscous bleach dye and a formulatedviscous accelerator compound are contained within a dual cartridge. Amixer assembly is in fluid communication with the combined cartridgeshaving a manifold conduit forming a mixing chamber, containing a mixinginsert, allowing a blended compound from the cartridges to be ejectedbetween the comb teeth. A lever actuator interfaced with the plungerrods permits precise volume control.

An important object of the invention is the ease of application sincethe distance of the space between the teeth is predetermined allowing awide swath to be dyed at the same time. The mix ratio is pre-selectedtherefore no handling of liquids or emulsion is required.

Another object of the invention is the use of a manual lever to regulatethe flow of the mixed formulation by simply squeezing the lever towardthe handle. A clicking noise is created as the lever ratchet arm strikesthe next tooth of the plunger permitting the user to remember the numberof clicks to produce the optimum amount of the mixture according to thelength of the hair to be hi' blighted.

Yet another advantage of the inventions use is that it saves money andtime, as it does not require professional application at a hair salonwith the only expense is that of purchasing the applicator comb at aconvenient time. A dual cartridge is supplied with the device originallyand the applicator comb is easily cleaned after use with water and asyringe pressurizing the internal conduits when the cartridge isremoved. The entire applicator comb is formed of a clear thermoplasticresin permitting visual indication that no mixed blend remains inside.Individual dual cartridges are available to the user in a variety ofcolors shades and tints.

A further object is that the comb invention is completely self containedrequiring no external mixing without any mess, and the only requirementis to install the dual cartridge into the mixing nozzle to have the combready for use.

An advantage of the invention is that the device is cost effective tostart with, as it would be almost equal to the cost of the dyecomponents itself. Since the dual cartridge is the disposable throw awayafter use type, therefore none of the paraphernalia normally requiredfor highlight hair is required to be stored only the applicator combitself.

Another object is realized by the use of a lever actuator which permitsa controlled rate of flow speed allowing a user to gently squeeze thelever handle with either the right or left hand permitting the desiredamount of mixed compound to be released as required for the application.

A further advantage is the ease of manufacture which utilizes theinjection molding process with the comb formed in two halves theninstalling each half of the mixer with the mixer inserts, the springloaded lever assembly, and the plunger rod in-between then bonding thehalves together.

Finally the hair highlighting applicator comb is reusable, as it onlyrequires a new dual cartridge which is readily available at the sameretailer that furnished the comb originally or other convenientretailers handling similar hair lightening materials.

These and other objects and advantages of the present invention willbecome apparent from the subsequent detailed description of thepreferred embodiment and the appended claims taken in conjunction withthe accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

The best mode for carrying out the invention is presented in terms of apreferred embodiment. This preferred embodiment of a hair highlightingapplicator comb 10 is shown in FIGS. 1 thorough 29 and is comprised of ahollow comb body 20 with a number of comb teeth 22 descending from thebody 20, and an access opening 24 is formed above the comb teeth 22, asillustrated in FIGS. 1 and 2.

The comb body 20 is formed in two separate side halves each havingopposed interconnecting means in the form of posts 26, pins 28 andsockets 30. The halves consist of a left side half 32, having the accessopening 24 above the teeth, and a right side half 34 in essentiallymirror image of the left side half 32, except for the access opening 24,and the opposed interconnecting means, 26, 28 and 30. The comb body 20includes a handle end 36 and a comb end 38 with the handle end 36 havinga linear opening 40 on an under side as illustrated in FIGS. 8 and 13,and a rectangular slot 42 on a distal handle end 36, as shown in FIG. 1.

The comb teeth 22 may be formed in any number preferably from 4 to 60teeth with 12 teeth found to be ideal. The teeth 22 are formed as a halftooth in the left and right side half 32 and 34 and are permanentlybonded together at the assembly of the comb body 20 each forming a denseand stiff tooth member.

A dual cartridge 44 is removeably positioned within the comb body 20through the access opening 24 and consists of a first tube 46 and asecond tube 48 connected longitudinally together. Each tube 46 and 48individually have one end formed with a reduced neck 50 and a nozzle 52and, an opposed end having a full diameter open end 54, as shown in FIG.27. A lifting tab 56 is integrally formed on a rear outside surface ofthe first tube 46, for lifting and removing the cartridge 44 from thecomb body 20. The cartridge tubes 46 and 48 each contain separatecompounds therein; with the first tube 46 having a viscous bleach dyecompound 58 of a selected color and the second tube 48 a formulatedviscous accelerator compound. It should be understood that the compoundsmay be reversed in the tubes 46 and 48.

A resilient dual mixer gasket 62, shown in FIGS. 3 and 26, is pluggedinto both the first cartridge tube nozzle 52 and second cartridge tubenozzle 52 at the same time when the cartridge 44 is inserted into theapplicator comb 10 through the access opening 24 sealing the junction.An individual resilient stopper 64 is placed in the full diameteropening 54 of each cartridge tube 46 and 48 with each stopper 64 havingan irregular shaped hole 66 therein for releasing air pressure when thecartridge 44 is originally filled with the liquid compound 60 and 62. Astopper plug 65 is inserted in the irregular shaped hole 66 to seal eachcartridge tube 46 and 48.

A dual plunger rod 68 has a number of rack teeth 70 spaced in a straightline, and the plunger rod 68 is slideably disposed within the comb body20 in linear alignment with the dual cartridge 44. The plunger rod rackteeth 70 face downwardly from the comb body handle end 36. A downwardlyangled gripping flange 71 is formed on a distal end of the dual plungerrod 68 which extends outwardly from the comb body 20 through therectangular slot 42 formed within the body, as illustrated in FIG. 1. Anextension spring 72 is attached between the comb body 20 and the dualplunger rod 68 which draws the plunger rod 68 into the dual cartridge 44while maintaining a linear force until incrementally released by manualoperation of a lever handle 74.

The lever handle 74 has a first end 76 and a second end 78, with thefirst end 76 pivoted onto the comb body 20 adjacent to the comb teeth22. A ratchet arm 80 pivotally engages the second end 78 of the leverhandle 74 with the ratchet arm 80 meshing with the plunger rod rackteeth 70. The linear opening 40 is sufficiently wide to receive theratchet arm 80 when engaging the plunger rod rack teeth 70 and the combend 38 is sufficiently wide to house the dual plunger rod 68 in a sideby side horizontal configuration. The lever handle 74 is pivotallyattached to the comb body 20 with the integrally formed post 26 having amating socket 30.

The ratchet arm 80, illustrated in FIG. 22, includes a few ratchet armteeth 82 configured to mate with the dual plunge rod rack teeth 70. Adowel pin 84, depicted in FIG. 25, pivotally attaches the ratchet arm 80to the lever handle 74. Further a torsion spring 86, shown in FIG. 24,is attached to the dowel pin 84 to urge the ratchet arm teeth 82 tocontinually mesh with the plunge rod rack teeth 70 until released by themanual compression on the lever handle 74 against the handle end 36 ofthe comb body 20.

A mixer 88 is in fluid communication between the dual cartridge 44 andthe comb teeth 22, which forces the separate viscous bleach dye andformulated viscous accelerator compounds 58 and 60 to blend togetherforming a paste. The mixer 88 consists of a mixer left half 90 and amixer right half 92, as illustrated in FIGS. 14, 15, 18 and 19, whichare permanently bonded and mated together prior to being placed withinthe comb body 20.

When the mixer left half 90 and the mixer right half 92 are matedtogether a mixing chamber 94 is formed, as shown in FIGURES. 15 and 18and a mixer insert 96 is installed. The mixer left half 90 and the mixerright half 92 each have an opposed manifold groove 98 therein, such thatwhen mated together form a complete manifold conduit connecting from thedual cartridge 44 through the mixer insert 96 in the mixing chamber 94,to a number of comb teeth root junctions 100 which are each spaced apartfrom a pair of the comb body teeth 22. While the number of teeth rootjunctions 100 may be any amount there must be at least two junctions100. A mixer top fitting 102, shown in FIG. 17, is positioned on thecombined mixer left half 90 and mixer right half 92 and is in fluidcommunication with the dual cartridge 44 and the mixing chamber 94.

The comb body 20, dual cartridge 44, dual plunger 68, lever handle 74,ratchet arm 82 and the complete mixer assembly 88, 96 and 102 are formedof thermoplastic resin selected from the group consisting of cellulose,phenolic, phenylene oxide, polycarbonate, polyester, polyethylene,polypropylene, polystyrene, acetyl, polyimide and poly vinyl chloride ina transparent, translucent or opaque visual category. Transparentthermoplastic resin is preferred

In operation the hair highlighting applicator comb 10 is used to streaka person's hair in a spaced highlighting relationship. The subject'shair should be dry and the cartridge 44 removed from the wrapper. Theplunger rod 68 is pulled out away from the handle end 36 until it stopsand the lever handle 74 is compressed into the handle end 36 where theratchet arm 80 pushes, by its spring loaded action, into the plunger rod68 in front of its integral rack teeth 70. The cartridge 44 is theninserted into the access opening 24 where the extension spring 72 urgesthe plunger rod 68 against the cartridge resilient stopper 64 but notsufficiently to expel any viscous bleach dye and formulated viscousaccelerator compound 58 and 60 at this time as the ratchet arm 80 hassufficient force to retain the plunger rod 68 from further movement.

When ready for use the lever handle 74 is pulled away from the combhandle end 36 and the comb 10 is drawn through the selected area of hairwhile simultaneously compressing lever handle 74 against the handle end36 of the comb 10 thereby releasing the mixed viscous bleach dye andformulated viscous accelerator compound 58 and 60 under the influence ofthe extension spring 72. When the handle 74 is manually pivoted upwardinto the comb body 20 the plunger rod 68 slides linearly forward, underthe urging of the ratchet arm 80, and compresses the cartridge 44interior forcing the blended compounds 58 and 60 to flow betweenselected comb teeth 22 in a controlled manner. A clicking noise iscreated as the spring loaded lever ratchet arm 80 strikes the next racktooth 70 of the plunger rod 68 indicating functional operation andvolume control of the blended, soft, homogeneous emulsion compound 58and 60 which is easily understood by the user.

When the process is completed and the mixed compound is depleted, thecartridge 44 may be removed by pulling the plunger rod 68 outwardly toits open at rest reset position with the lever handle 74 compressed, atthat point the cartridge 44 may be detached through the access opening24 by gripping and pulling on the lifting tab 56.

The entire comb 10 may be easily cleaned with water after use, however asyringe filled with water for pressurizing the internal conduits may berequired in some special circumstances. As the entire applicator comb 10is formed of a clear thermoplastic resin visual indication that noindividual compound or viscous bleach dye mixture still remains inside.Replacement dual cartridges may be obtained in a variety of colorsshades and tints.

While the invention has been described in complete detail andpictorially shown in the accompanying drawings, it is not to be limitedto such details, since many changes and modifications may be made to theinvention without departing from the spirit and scope thereof. Hence, itis described to cover any and all modifications and forms which may comewithin the language and scope of the appended claims.
